My continuing overheating saga

Bill V:

It is now 12:45PM. I have finished 6 beers, and the car is still overheating . I think I will give the edelbrock water pump a try before pulling the heads.

Mike:

Here is a chronology and the symptoms.

I fired the motor with the body off and broke in the cam for about 20 minutes. The temperature at fast idle with both the 14" fan and an auxillary fan was between 190 and 200. After I shut down and restarted and blipped the throttle a bit the temperature climbed to over 220 and I shut it down. I did find that I did not have the proper t-stat and that has been changed. I did also change out the fan to the one you recommended and refilled the system with water and a bottle of water wetter. I started the car again and the temperature climbs to 180 and stays for a few minutes at idle. The electric fan comes on at 190 but then the temp continues to climb. I let it cool down and then drove the car for a few miles at 40+ mph. Temp continues to climb. I dont believe that it is the fan or radiator. The radiator is relatively new and had been cleaned during my rebuild a year or so ago. It flows well when I put a hose thru it. While I dont notice any bubbles in the upper line when I remove the cap, it does surge as I increase rpm but I am thinking that is just a function of increased flow at higher rpm. I am going to check the jets for sizing and pull some plugs to see what they look like and repost. If this car wasnt so pretty I would put the cover on it and forget about it for a while! I am geting pretty pissed and frustrated.
